ADDING TYPE WRITER.

Specification of Letters Patent.

Patented Jan. 24,1911.

To all whom it may concern:

Be it known that I, JERE G. ICINGSBURY,

a citizen of the United States, residing at Orange," in the county'of Essex and State of New Jersey, have invented certain new and useful Improvements in Adding Type- \Vriters, of which the following is a specification. v

The present invention relates to improvements in combined ty pewriting and adding machines and particularly to such machines wherein are provided two or more adders,

each comprising a plurality of adding wheels and carrying means, and will be hereinafter more particularly described in connection with the accompanying drawings, in which,

Figure l is a sectional elevation through one of the adders of such a machine, a portion of the actuating means being also shown; Fig. 2 is a plan view illustrating two adders and the means for resetting, or restoring to zero position, the wheels of such adders; Fig. 3 is a detail view.

In machines of the class to which the pres ent invention relatesyit has been found desirable to provide a plurality of'independent adding mechanisms so that figures may be written in two or more columns and the sum of the numbers in any column instantly ascertained, the numbers being accumulated on the adding mechanism appropriated to that.

column as the corresponding figures are written. The action .of all of the adding mechanisms is controlled by a common key actuated mechanism and means are provided.

for etfecting a relative movement between the adders and such key actuated mechanism to bring any desired adder into operative relation with said mechanism.

Bya key actuated mechanism, as herein used, I mean the parts operated on depressing a key to'actuate van adder, whether the movement of'the key is directly conveyed to the adder or whether it is the means of otherwise operating the adder.

In some forms of adding mechanism the wheels are automatically locked following each movement resu ingfrom a carrying operation and cannotabe turned or actuated further without resetting -the carrying means. Means are provided for automatically resetting the carrying means prior to actuating the adder but where there are several adders the only one afi'ected by such automatic restoring device is that which is ing means of the tion. 1 v

While the adding mechanism may be of thenin operative relation to the key actuated mechanism. It is desirable, in order to With such an arrangement of parts, however,

it will be seen thatas the automatic restoring device is only operative on' the carrying means of one adder it maybe impossible to'actuate the means for turning the wheels to Zero position. because one or more of the wheels of an adder which is in inoperative relation to the key actuated'mechanism is locked by its associated carrying means. To avoid this and provide means whereby a single, or common, actuator may be employed for turning the wheels of all of the adders to zero position without'the necessity of first bringing each of the adders into op erati'verelationj to the key actuated mechanism, I provide each adder with a detent which may be adjusted to retain the carry difl'erent constructions, I have shown in the drawing one which has proved effective In which each adder mechanls'm is in a case X adder in inoperative posiand has adder wheels C with connected pin- .ions 9 gearing with gears A which may be turned by pinions K when either of the latter is engaged by a toothed sector N, this sector being moved as the result of operating the number keys of the instrument.

'The carrying mechanism consists of ratchet wheels B with which engage pawls E on frames D each carried by swinging links 5, the-frame being'carried in one direction by a spring G toturn the associated ratchet one step, and moved in an opposite direction at each operation of the mechanism by a reciprocating striker Q-operated-from any part of the 'machine. Normally each frame Dfis held in position, after being pushed, back by the I striker, by a detent F having two armslf; g, the arm f being brought by a spring 3 opposite the shoulder hot the frame, acting as a 'stop( The arm g has a beveled end, and each wheel A has a lug b (or two lugs when the said wheel is twice the diameterof the pinion p), and

is'that associated with the. next wheel higher in denomination to that having the lug b which swung the detent F. Each pawl E Tin moving forward engages by an arm 8, the lower edge of one of the teeth of the ratchet which has been turned, and in its forward position thus locks the ratchet so that it cannot be turned so long as the frame D is in its forward position. If, therefore, thereis a plurality of adders the wheels of all except that where the locking means are pushed back by the pusher are locked and only that coacting at the time with the adder keys can be set to zero. I, therefore, combine with each adder a detent which can be set so as to push'and hold back the frame and its pawl or other locking element of the carrying device.

As shown a rock shaft 1 of each case carries an arm 3 and is provided at the side of the case with a. handle 4, the latter in such a position that when swung to the left as in dotted lines Fig. 1, the arm 3 will be carried against the rear set of links 5 attached to the resetting bars I) and thereby swing the pawls E out of locking posit-ion.

. Any suitable means may be used for holding the arm din place, as by using a spring arm 4 which may be sprung overa stop lug (3, Fig. 3 or away therefrom topermit the arm to be swung past the lug, the said arm being carried to the right when the. adder is brought opposite the operating sector. A sockctat the top of each arm 4 permits it to be shifted by inserting the point of a stylus or pencil therein.

..\n v suitable means may be employed for turning the adder wheels to zero. Thus a shaft S passingthrough all the gears A of all the adders has a shoulder as adapted to engage with pawls j on the gears, and as the shaft is turned, its shoulder will .strike the pawls of the wheels out of osition and successively picking them up will bring all to zero. The shaft S may have a knob a at the end, or may be provided with other means for facilitating its rotation.

\Vithout limiting myself to the precise arrangem utt of parts shown, I claim:.

I. In a'machine of the character described.

the combination with a plurality of adders, each comprising a series of adding wheels and coacti'ng carrying means adapted in one position to lock said adding wheels, a common actuator for all the adders, and a resetting device adapted to 'cotiperatewith all of the adders, of means adjacent each adder for retaining the said locking means thereof in inoperative position, substantially as and for the purpose described.

In a machine of the character described, the comhinatitm of a plurality of adders, each comprising a series of adding wheels, and means adapted to lock the adding wheels, an actuator, independently adjustable means on each adder for rendering the locking means of that adder inoperative, and a means common to all of the adders for turning the wheels thereof to zero position.

3. In a machine of'thc character described, the combination of a plurality of adders, each comprising a series of adding wheels and means adapted to lock the adding wheels, an actuatcr, a rock shaft in each adder having an operating-arm at one side of the adder, means connected with said shaft for moving the lockingdevices of the adder to inoperative position, and a means common to all of the adders for turning the wheels thereof to zero position.

4. In a machine ofthe character described, the combination of a plurality of adders. each comprising a series of adding wheels and means adapted to lock said wheels, means on each adder for rendering the loclring devices thereof inoperative. a shaft extending through all of the adders, and means whereby to turn all of the adding wheels to zero position by actuating said shaft after the locking devices have been rendered inoperative.

5. In a machine of the character described. the. combination of a plurality of adders, each comprisiir a series o adding wheels and carrying means adapted to lock the adding whee-ls. means on each adder for releasing the adding wheels thereof from said lock. and a shaft adapted to turn the wheels of all the adders to zero position.

In testimony whereof I ailixjnrv signature in presence of two witnesses.
